Description
Technical field
The present invention relates to the communications field, relate in particular to a kind ofly in group service, carry out the method for channel resource allocation according to cluster user call type and call business.
Background technology
The relative cluster private network of cluster common network has outstanding advantage at aspects such as networking and maintenance costs, so the cluster common network is the development trend of group system; Because gsm system is to have the public mobile network on wide variety of user basis the most in the global range, therefore development is certain selection of China's group system based on the group system of GSM, such as: the GT800 system that China has independent intellectual property right is exactly a group system of new generation.
The service object of group system is some cluster departments, as: public security, fire-fighting, the People's Armed Police, national security agency, army, departments such as large-scale enterprises and institutions, because the service object of group system is not the general public, therefore determined that the relative public network user quantity of number of users of group system is very limited, because lacking widely, the user supports, therefore the investment of group system is very limited, this has just determined the Da Qu system of group system, and (coverage radius of cell is big, can significantly reduce website quantity), cell channel resource anxiety characteristics such as (can significantly reduce frequency resource require and the web construction cost), because all users share very limited channel resource in the Da Qu, and these users have different calling authorities; Therefore, realize realizing that according to service priority Resource Allocation in Networks is the basic function of group system.As shown in Figure 1, be in the prior art, a system schematic of cluster common network, as seen from the figure, this system mainly on the prior mobile network basis, has done certain change, to finish the cluster network function.
Because the cluster common network provides group service for a plurality of cluster department,, the situation that different cluster departments has different priority sequences therefore just occurred and taken place because there is different requirements in each cluster department for miscellaneous service aspect the priority.For example: for the A of cluster department, its type of call priority of resource allocation order be from high to low emergence call service=the broadcast ﹠ call business=group-calling service=the individual calling business=the duplex telephony business=data service; And for the B of cluster department, its type of call priority of resource allocation order be from high to low emergence call service=group-calling service=the individual calling business=the broadcast ﹠ call business=the duplex telephony business=data service.The maintenance console configuration of above-mentioned precedence information by MSC, and being set on the MSC main frame in view of the above can be in the group service process, provides corresponding service according to the priority orders of this setting.
In the cluster common network, for example gsm system has been realized the priority feature based on concrete business, promptly strengthens multipriority and seizes business, is called for short the eMLPP business.EMLPP is professional to carry out channel resource allocation according to the concrete call business eMLPP priority setting of initiating, each user selects a signatory priority the professional permission of signatory eMLPP user when making a call, different priority has determined the call setup duration, to the characteristics such as the ability that takies of resource.Operator provides different service quality according to the priority that the user contracts for different users, different callings.
EMLPP is professional to define 7 priority levels (A, B, 0,1,2,3,4) altogether for calling out, and wherein the A level is highest, and 4 grades is lowermost level.Two the highest priority are that network internal is used reservation, only can use in this locality.If outbound call has taken place, A, B priority need be converted to 0 grade.
The user can contract a priority conduct from operable limit priority in network in HLR, two priority of A, B are that network internal keeps, and do not allow domestic consumer signatory, and this subscription data is determined by Virtual network operator;
User's default call priority of can contracting in HLR, this priority can not be higher than the limit priority that the user contracts, and allows the user to revise this priority by the operation of terminal.
When the user makes a call the priority of designated call not, network will be called out by default priority and handle.
The eMLPP scheme of gsm system has following shortcoming:
1, priority can not realize realizing the Internet resources priority assignment based on type of call based on concrete call business; For example: group calling priority has identical authority with point to point call priority, and for some cluster departments, group calling priority is enjoyed higher priority authority than point to point call when resource allocation;
2, call priority limited amount, whole system have only 7 priority levels to use for all cluster users, can not satisfy the definition demand of different cluster department for priority;
3, can not realize that different cluster department realizes the different requirements of Internet resources priority assignment for type of call.
Summary of the invention
The invention provides the method for carrying out channel resource allocation in a kind of group service, have the problem that can not realize carrying out the Internet resources priority assignment in the prior art based on type of call in order to solve.For this reason, the present invention adopts following technical scheme:
Carry out the method for channel resource allocation in a kind of group service, described group system comprises that storing cluster user strengthens multipriority and the attaching position register (HLR) of seizing business (eMLPP) precedence information, mobile switching centre (MSC) with allocation cluster user profile, and be the base station sub-system (BSS) of cluster user Resources allocation, it is characterized in that:
VPN(Virtual Private Network) information under the signatory cluster user in HLR, and each Virtual Private Network call resource type distribution priority allocation list is set in MSC, be provided with the priority of resource allocation of VPN in this allocation list to each type of service;
When cluster user is initiated trunked call, may further comprise the steps:
The cluster user sign that A, MSC report by travelling carriage is obtained the VPN information of the cluster user that makes a call;
B, MSC search type of call priority of resource allocation allocation list to obtain priority of resource allocation information by described VPN information and call type;
C, MSC carry this type of call priority of resource allocation information to BSS system transmitting channel resource request in this request;
D, BSS carry out resource allocation according to type of call priority of resource allocation information and eMLPP precedence information.
In the described steps A, described user ID can be IMSI International Mobile Subscriber Identity (IMSI) or Temporary Mobile Subscriber Identity (TMSI).
In the described steps A, described VPN information, the VPN information of inquiring about the cluster user that VLR Visitor Location Register (VLR) obtains for MSC by user ID.
In the described steps A, when location of mobile station changes, described VPN information, the VPN information that refreshes to VLR for HLR.
Among the described step C, described channel resource request can comprise voice group call service assignment request, the assignment request of voice group call service or handoff request etc.
Among the described step D, described type of call priority of resource allocation is higher than eMLPP priority.
Among the described step D, when the type of call priority of resource allocation is identical, carry out resource allocation according to eMLPP priority.
Type of call priority of resource allocation information in the described type of call priority of resource allocation allocation list is carried with the byte of 8 bits.
Described cluster user is only signed the VPN under in the of in HLR.
The calling of initiating when described cluster user is when striding the calling of VPN, and described call business resource type is distributed priority, for the call business resource type of the signatory VPN correspondence of this cluster user is distributed priority.
The present invention program's introducing, make and realized that in cluster common network system different cluster department has different type of call Resource Allocation in Networks priority for different type of calls, can determine user resource allocation jointly based on type of call and call business, make that group service is flexible more, function is more complete.。For example: for the A of cluster department, its type of call priority of resource allocation order be from high to low emergence call service=the broadcast ﹠ call business=group-calling service=the individual calling business=the duplex telephony business=data service; And for the B of cluster department, its type of call priority of resource allocation order be from high to low emergence call service=group-calling service=the individual calling business=the broadcast ﹠ call business=the duplex telephony business=data service.

Fig. 1 is a system configuration schematic diagram of the present invention;
The schematic flow sheet that Fig. 2 makes a call for cluster user of the present invention.
Embodiment
Below in conjunction with Figure of description the specific embodiment of the present invention is described.
As shown in Figure 1, be the cluster common network system configuration schematic diagram of a simplification of the present invention, as seen from the figure, network environment of the present invention can comprise:
Store cluster user and strengthen multipriority and the attaching position register (HLR) of seizing business (eMLPP) precedence information;
The mobile switching centre of allocation cluster user profile (MSC);
VLR Visitor Location Register (VLR);
And be the base station sub-system (BSS) of cluster user Resources allocation.
Therefore here MSC and VLR often are an entity physically, but are different network elements in logic, and it being write as the MSC/VLR mode do not have yet can not.
The present invention signs VPN(Virtual Private Network) information under the cluster user in HLR, the VPN of each user signatory own institute subordinate in HLR here, the signatory simultaneously VPN of each user.Such as public security officer signatory VPN in HLR can only be the VPN of public security bureau, and fire fighter signatory VPN in HLR can only be the VPN of Fire Department.
When location of mobile station changes, the latest data after upgrading is refreshed to VLR Visitor Location Register (VLR) VPN that contracts comprising travelling carriage.
In addition, each Virtual Private Network call resource type is set in MSC distributes the priority allocation list, be provided with the priority of resource allocation of VPN in this allocation list each type of service.The priority of resource allocation information of above-mentioned type of service can dispose by the MSC maintenance console.
The present invention is provided with a vpn service resource type and distributes the priority allocation list in MSC, this table has provided each VPN group to various types of traffic (emergence call service, broadcast ﹠ call business, group-calling service, individual calling business, duplex telephony business, data service etc.) priority of resource allocation (Service Priority) value; This Service Priority value is carried with 8 common binary values, represents the service priority height; BITs is many more, and priority number is many more, and vice versa.
The present invention is set at 8 BITs with Service Priority territory, and so in fact 256 values can be arranged.In addition, the present invention can be provided with urgent call, voice group call service (VGCS), voice group call service (VBS), individual call (VPCS), the common point to point call (PTP) of all VPN, the Service Priority default value of circuit type data service (CSD) is 128, when in VPN group specific demand being arranged like this, the priority of resource allocation order of can floating up or down flexibly.Because these 8 binary systems are 0～255, default 128 are expressed as a middle priority, when being provided with concrete priority can height can be low, can have maximum elasticity like this.Such as can when specifically needing to change priority, carrying out priority skew deletion.
As shown in Figure 2, be when the schematic flow sheet of cluster user at the Mobile Origination trunked call, as seen from the figure, mainly may further comprise the steps:
The cluster user sign that S1, MSC report by travelling carriage is obtained the VPN information of the cluster user that makes a call.
In calling procedure, MS reports IMSI or TMSI identity information in layer three message fully in article one, and MSC inquires about the VPN that VLR obtains this call initiator, (when travelling carriage upgraded in the position, HLR refreshed the VPN of travelling carriage to VLR) by IMSI or TMSI.In based on GSM, the identity of travelling carriage is exactly to characterize by IMSI or TMSI, generally be to carry in article one layer three message, so that network side obtains the travelling carriage identity rapidly, VPN is the information of user in the network side registration, in HLR, store, when travelling carriage upgrades in the position (when the lane place changes), HLR can refresh user's relevant information to VLR, the VPN of user's registration is also included within wherein, therefore, MSC obtains the VPN information of user's registration by subscriber identity information (IMSI or TMSI) inquiry VLR.
S2, MSC search type of call priority of resource allocation allocation list to obtain priority of resource allocation information by described VPN information and call type.
After MSC obtains VPN,, inquire about the priority of resource allocation Service Priority of this call business by type of service priority of resource allocation allocation list by this VPN and type of call.
Among the present invention, type of call can determine according to Setup message or Immediate Setup message, can be provided with such as us shown in the following form of Immediate Setup of cluster urgent call:
| Source identity | Cell | Type/reference | Whether necessary | Form | Length |
| 0x03 | Protocol-identifier | The call control protocol authenticator | Necessary | Thresholding | 1/2 |
| Transaction identifiers | Transaction identifiers | Necessary | Thresholding | 1/2 | |
| 0x0a | Type of message | message type | Necessary | Thresholding | 1 |
| The nybble free time | The nybble free time | Necessary | Thresholding | 1/2 | |
| Ciphering Key Sequence Number | Ciphering Key Sequence Number is with reference to GSM 04.08,10.5.1.2 | Necessary | Thresholding | 1/2 | |
| Travelling carriage class mark | Travelling carriage class mark 2 is with reference to GSM 04.08,10.5.1.6 | Necessary | Length+thresholding | 4 | |
| The travelling carriage identity | The travelling carriage identity is with reference to GSM 04.08,10.5.1.4 | Necessary | Length+thresholding | 2-9 | |
| Keep |
Here most critical is the definition in following territory, has determined type of call:
| 0x0a | Type of message | Type of message | Essential | Thresholding | 1 |
S3, MSC carry this type of call priority of resource allocation information to BSS system transmitting channel resource request in this request.
MSC is to BSS system transmitting channel resource request, this channel resource request comprises voice group call service (VGCS) assignment request, channel resource solicited messages such as voice group call service (VBS) assignment request and handoff request are carried this type of call priority of resource allocation ServicePriority in the channel resource request message.
S4, BSS carry out resource allocation according to type of call priority of resource allocation information and eMLPP precedence information.
BSS carries out resource allocation according to Service Priority and eMLPP priority, seizes according to Service Priority and eMLPP when resource is nervous and lines up, and in the solution of the present invention, sets the ServicePriority territory and has precedence over the eMLPP territory; And when Service Priority thresholding is identical, carries out resource allocation, seize or line up according to call priority eMLPP thresholding.Under the situation such as channel resource anxiety in the sub-district, receive a urgent call, if the Service Priority territory of urgent call and common point to point call has identical setting, then urgent call (eMLPP priority height) can be seized the shared channel resource of common point to point call in the sub-district (eMLPP priority is low).
In the solution of the present invention, there is a kind of processing of special case situation, promptly be to handle for the group calling situation of striding VPN group.Domestic consumer initiates to stride Virtual Private Network call, the Service Priority thresholding of this call business is got the VPN corresponding service priority that this user contracts, stride VPN group calling keeper and initiate to stride the VPN corresponding service priority that the VPN group calling is also contracted with this keeper, if this keeper can initiate a plurality of VPN of striding group callings, because the service priority Service Priority of these group callings is identical, therefore, concrete priority of resource allocation of initiating to stride the VPN group calling is eMLPP territory decision of being striden the VPN group calling by each.
The present invention program's introducing, make and realized that in cluster common network system different cluster department has different type of call Resource Allocation in Networks priority for different type of calls, realized determining jointly the scheme of user resource allocation based on type of call and call business.For example: for the A of cluster department, its type of call priority of resource allocation order be from high to low emergence call service=the broadcast ﹠ call business=group-calling service=the individual calling business=the duplex telephony business=data service; And for the B of cluster department, its type of call priority of resource allocation order be from high to low emergence call service=group-calling service=the individual calling business=the broadcast ﹠ call business=the duplex telephony business=data service.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
